EASA can pass a regulation that all pilots must wear pink knickers with frills for all I care they still have to operate with existing EU employment , discrimination and human right laws.
Unless they can show that pilots who pass medicals over the age of 60 are falling out of the skies and are a danger then those people have equal employment rights to anyone else.
Sadly someone has to challenge them or at least scare them enough so that they back down as they have with third country licences which have been postponed twice as some of that contravenes employment laws.
